How to say this

[manalnor]

Hello friends,

 

it is very complicated and spent alot of time thinking and i can not do it

 

let say we have 2 tables

 

Table1 (id,user,code) example

 

(1,user1,code1)

(2,user1,code2)

(3,user2,code3)

(4,user3,code4)

 

this means user1 has added code1 and code2

 

Table2 (id,code,hits) example

 

(1,code1,100)

(2,code2,50)

(3,code3,40)

(4,code4,80)

 

this means code1 has 100 hits and code2 has 50 hits

 

I wanna get [ the sum of hits of codes that added by only user1 ] it will be 100+50=150 Hits

 

i've an idea

1- query for all codes added by user1 at table 1

and keep the results as array and it should be (code1,code2)

 

2- then get the sum of hits for all codes in that array (code1,code2) from table 2

 

Now the problem  how to say it in MYSQL

 

thanks

Since the number of hits are associated with the code, why have two tables? Just add the hits column to table one. Then to find total hits to one person query an ADD hits WHERE user = user1

Seems more of a SQL question rather than PHP, moving.

read the tutorial of phpfreaks about joins, I am pretty sure that is what you need.

Hi

 

Something like this would do it

 

SELECT user, COUNT(hits)
FROM Table1
INNER JOIN Table2
ON Table1.code = table2.code
GROUP BY user

 

All the best
